What creature or artifact would you create? (Heroes IV)

Although... maybe we shouldn't create that artifact I mentioned. Instead, it would be better to create an amulet that enhances the effect of any magic. If we're going to create artifacts, we should also create creatures! The best approach would be to create improvements for creatures that can be recruited in cities. Let's take Haven as an example: Halflings - Siege Engineers (shooting stones and generally not like in Warcraft 3) Dwarves - Master Craftsmen (who can repair equipment during battle - golems, ballistae, catapults) Golden Golems - Diamond Golems (reflecting enemy spells) Mages - Archmages (as expected, they possess a large set of spells)... And so on.
